Application filed November 1, 1905. Serial No. 285,465.

To all whom it may concern:

Be it known that I, CHARLES A. BERRY, of Stamford, in the county ofFairfield and State of Connecticut, have invented certain new and usefulIm rovements in Combined Rim and Mortise l declare the following to be afull, clear, and

" ject exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in combined rim and mortise lock,the 0b of the invention being to provide a simple and eficient lock thatcan be applied to a door without any" extensive or etri mental cutting.

'A further object is to provide a lock of comparatively simple andinexpensive structure, in whichthe latch bolt may be dead locked againstmovement by the outside knob, or against both knobs and key, thus makingit possible to deadlock the bolt against the holder of a key to thelock.

With these-and other ends in view my inventi-on consists in the partsand combinations of parts and in the details of construction that willbe more fully explained and pointed out in the claims.

In theaccompanying drawings, Figure 1 is a view in elevation of theinner face of the lock showing the bolt free to be actuated by eitherknob or the key. Fig. 2 is a view in longitudinal section on the linew-w showing the lock applied to a door. Fig. 3 is a similar View intransverse section on the line 31- of Fig. 1. Fig. 4 is a View in frontelevation. Fig. 5 is a view in elevation of the inner face of the lockshowing the bolt in its keeper and the outer knob deadlocked. Fig. 6 isa view showing the knob and key mechanisms deadlocked. Fig. 7 is a viewshowing the latch bolt retracted by the inner knob. Fig. 8 is aperspective view of the latch bolt. Fig. 9 is a similar view of thestrike plate or keeper. Fig. 10 is a view of the deadlocking mechanismfor the outer knob, and Fig. 11 is a view of the meeting ends of theknob spindles. Fig. 12 is a- View in side elevation partly in sectionshowing another form of deadlock for the latch. i 13 is a view in planof same showing 1: e dead locking tumbler in the position it occupieswhen the door is open, leaving the latch bolt operative and Fig. 14

ocks; and I do hereby is a similar view showing the dead locking tumblerbeing raised by the outer knob.

The lock casing consists of a rectangular section 1 provided centrallyat its front edge with a forwardly projecting portion 2 which latterforms the housing for the latch bolt 3. This portion 2 of the casing isprovided at its outer edge with a right angled flange 4:, which latteris designed to rest within a mortise in the edge of the door, and isprovided with an opening in which the latch bolt rests and moves.Connecting the flange 4.- with the sections 1 and 2 of the lock casing,are the triangular shaped ribs 5. These ribs are preferably castintegral with the plates 1 and 2, and rest on opposite sides of thebolt, and within a correspondingly shaped mortise formed in the front atthe outer edge of the door.

Sections 1 and 2 of the lock casing, are provided with a dependingflange 6 which extends from one end of flange 4:, around sections 2 and1 to the other end of flange 4, as shown in Fig. 1. This flange 6, is ofsuilicient depth to house the lock mechan-- ism, but as the latter issimple with few overlapping parts, the casing thus formed iscomparatively shallow, and when applied to a door all the mechanism ofthe lock rests to the outside of the inner face of the door, as clearlyshown in Fig. 2.

The locking bolt is composed of the pivoted or rocking section 3, thesliding section 7 and the pivotedtongue 8. The section 3 is hollowlongitudinally and open at its top to receive the pivoted tongue 8 andthe sliding section 7. The tongue 8 is pivoted to the section 3 near thepivot of the latter and conforms in shape to the contour of the outeredge' of the rocking section 3 of the bolt, so that when the parts arein their normal positions, the-outer face of the tongue rests flush withthe outer face of section 3. The sliding section 7 is also pivoted at 9to the rocking section 3, and is rigidly secured at its rear end tosliding stem 10 of the locking bolt. When the bolt is in its noriualposition this sliding section stands out beyond the face of the rockingsection 3 as shown in Fig. 3. lVhen the locking bolt is retracted, thepivot 9 of the sliding section moving in the are of a circle concentricwith the pivot of the locking bolt, causes the sliding section to moveinwardly or away from the strike plate of the kee er 12, and as the boltenters the keeper, t is sliding section is forced outward y into contactwith the strike plate which tends to pull the door tight against itsstop in the act of closing.

The pivoted tongue 8 is pivotally connected at 13 with the sliding plate14. This plate 14 rests adjacent to the sliding section 7 of the lockingbolt, and is provided with a bent end 15 which passes through anelongated slot 16 in the stem 10 of the bolt. It will thus be seen thatwhen the stem 10 is drawn inwardly, the locking bolt as a whole willturn on its pivot 17 and be retracted, and when the stem is released,the parts will return to the position shown in Fig. 3.

Pivotally mounted on screw 18 secured to plate 1 of the casing, is thedeadlocking lever'19, the outer end of which rests just in rear of theshoulder 20 of the stem 10 of the latch bolt. When the parts are intheir normal position as shown in Fig. 3, the rear end of plate 14,(which as before explained is pivotally connected to the tongue 8) restsagainst shoulder 20 on the stem 10 of the bolt, and the side of theplate 14 rests flush with the side of stem 10, the two parts forming abearing against which the toe 21 on deadlocking lever 19 slides. As thedoor is closed, the centrally located tongue 22 on the strike platekeeper 12, engages the pivoted tongue 8 of the latch bolt and moves sameinwardly as shown in Fig. 5, thus carrying the face of plate 14 againstwhich toe 21 of lever 19 bears, rearwardly, permitting the toe to movein behind shoulder 20 on the stem 10, and deadlock the latch bolt, andrevent it from being retracted b a knife b ade or other instrument introuced between the keeper 12 and flange 4 of the lock casing. When howeverthe latch bolt is moved by one of the knobs or its key, the shoulder 23on the movable .end of lever 24 engages the cam shaped end 25 of lever19, thereby withdrawing the toe 21 of lever 19 from behind shoulder 20and leaving the latch bolt free to be retracted.

Plate 14 connected to the pivoted tongue 8, is normally restrainedagainst inward movement by the spring 26, while the stem 10 of the boltis yieldingly held in its normal position by the spring 27.

Pivotally mounted on the sleeve 28 is the lever 24. This lever is cutaway to receive the knob, s indles, and hubs of the cams 29 and 30 an isprovided with the shoulders 23, 31 and 32. The shoulder 23, as beforeexplained actuates the lever 19, and also engages thetoe 33 of the stemof the latch bolt, so that when said lever 24 is turned by either knob,or key the shoulder 23 enga 'ng the toe 33 retracts the bolt. The shouder 31 and' 32 of lever 24 are engaged by; the opposite ends of cams 29and 30, so t at a the toe 45 thereof turning movement of either knob ineither gigection, will turn lever 24 and retract the o t.

The knob spindle, is made in two sections 34 and 35 revolubly connectedend-to end, so that either knob and its section of spindle may be turnedwithout the other. The section 34 of the spindle passin through the doorcarries cam 29, while t c section 35 of the spindle which passes throughlock casing carries cam 30.

Cam 29 is provided on its edge with a recess 36 in which lug 37 on thecam locking lever 38 is moved to deadlock the latch bolt against theouter knob 39. This lever 38 is pivoted at 40, and is actuated by thelug 41 on spindle 42, the latter being provided with the small fingerknob 43. By turning knob 43 lug 37 can be moved into recess 36 of cam 29and positively deadlock the latch bolt against the outer knob 39.

Lever 24 may also be actuated by a key lock 4O shown in Fig. 2. Thislock is of the pin tumbler variety and its key cylinder is connected bythe extension piece 41 with the rotary post 42 carried by the casing.This post is slotted at its outer end to receive the extension piece41*, and hence necessarily turns when the lock is actuated by its key.This post is provided at its lower end with a cam 43 adapted to engagetoe 23 of lever 24 for retracting the latch bolt, and with a cam 44adapted to engage toe 45 of the slide 46. This slide is actuated by abutton 47 and when moved as shown in Fig. 6, revents rotation of thepost 42*, while the ower end of slide passes to the rear of lever 24,thus not only deadlocking the latch bolt against the key, but alsoagainst both knobs. With this construction, button or stop 47 may beoperated when the door is open, thus dogging the operation of the knobsand key, but at the same time leaving the latch bolt free to move, sothat the door may be closed, but when the door is once closed all theunlocking elements of the lock remain inoperative until the stop hasbeen removed, thus releasing the knobs and key mechanism, so that theymay again operate.

The lock casing is provided on its inner face with two integral hollowsleeves 28 and 28, preferably short tubes forced over stumps on theplate 1. These sleeves are adapted to receive the posts 48 formedintegral with the escutcheon plate 49. This late fits against theoutside of the door, whi ethe casing carrying the locking mechanism issecured to the inner face of the door, and the parts are securedtogether by the screws 50 passing through the casin into posts 48. Bythis arrangement the Fool: can be applied to a door of anythickness notless than the length of sleeves 28 and 28, the extension piece 41carried by the lock, being of sufiicient length latch bolt and thekeeper. In this construction instead of em loying a swinging tonguecarrying a plate lihving ashoulder against which a toe on a lever abuts,I provide the sliding plate 7 resting against the flat face of thesliding section 7 of the latch bolt.

This plate 7 normally rests with its outer end flush with the outer endof the latch bolt 3, and is provided with a lip 7 which latter isdesigned to engage a portion of the strike plate on the keeper as thedoor is closed and be moved inwardly by such contact. The inner end ofthis plate 7 a is provided with a bent end 7 which latter passes througha cam slot 19 in the deadlockin tumbler 19. This tumbler 19 is pivotedto the stem 10 of the bolt 3, the bent end 7 passing through a slot insaid stem. The tumbler 19 is forced in the direction of the knobs by thespring 19 and is provided at its free end witha shoulder 19 which latterwhen the door is closed and the parts in their normal position rests inline with the shoulder 20 and absolutely prevents an in ward movement ofthe latch bolt.

As shown in Figs. 13 and 14, the tumbler 19 is in a position to permitof a rearward movement of the latch bolt, the shoulder 19 being in aplane above the path of shoulder 20*; In Fig. 13, which represents theposition of the parts when the door is open, it is shown held inunlocking position by the spring 55 which when unopposed holds the plate7 as shown in Fig. 12, with the end 7 thereof bearing against theinclined wall of the cam slot 19*. As soon however as the door isclosed, the flange 7 b of plate 7 engages the strike plate of thekeeper, and forces plate 7 and its bent end 7 inwardly, and as the bentend enters the inclined portion of the cam slot, it releases the tumblerl9 thus permitting the latter to drop until its shoulder 19 is in aposition to engage the shoulder 20. v

In Fig. 14 the tumbler is shown elevated by the cam 29 engaging andmoving the lever 24. In this figure the cam 29 is shown in the act ofturning, the toe 31 of said lever having engaged the depending shoulder19 of deadlocking tumbler 19*. This shoulder 19 is of suflicient lengthto rest on toe 31 during the continued opening movement of the cam 29and thus hold the dead locking tumbler elevated until the knob has beenreleased.

To apply this lock to a door it is simply necessary to mortise the edgeto receive the flange and triangular section of the casing,

king the latch against movement,-

and bore four holes for the sleeves, lock and knob spindles. By means ofthe improvements described,

the latch bolt when in its locking position,

may be deadlocked against the outer knob, or deadlocked againstbothknobs. and the key mechanism and also against any instrument introducedagainst the bolt between the keeper and the lock casing.
